It isn't a stupid question for a 13 year old. Please be respectful.
I heard weed could stop a guy from getting a girl pregnant. My friend used to smoke it and never got her pregnant. Til he started probation and couldn't smoke anymore and she got pregnant...I don't know if its true or not
Also weed to hurt the baby as well.....
And I am not trying to sound mean but at 13, you can not be mentally prepared for the responsibilities of having sex. I think you should discuss sex with your mom or an adult woman you are close to. They could help you.
Weed lowers sperm count for some males.However, it only takes one sperm to become pregnant. So yes, you could be pregnant. Weed is not and has never been considered a birth control. It probably causes more pregnancy than prevents. Lol.
I'm pretty sure I've read and heard that smoking weed makes a guy more fertile. Idk where you heard smoking can prevent you from getting pregnant but that is very wrong. If it was close to your ovulation day then yes there is a chance of pregnancy.
Smoking weed will not prevent you from getting pregnant. Since you had unprotected sex, yes you can be pregnant.
